WA-SHBOILER ATTACHMENT, I

SPECIFICATION forming part of Letters Patent No. 612,788, dated October18, 1898.

Application filed August 26, 1898: Serial No. 689,623. (ModeL) To aZZwhom it may concern:

Be it known that I, AUGUST RANTALA, a. citizen of the United States,residing at Navarro, county of Mendocino, State of California, haveinvented an Improvement in Washboiler Attachments; and I hereby declarethe following to be a full, clear, and exact description of the same.

My invention relates to a device which is especially applicable for usewith washboilers to keep the clothes in positionin the lower part of theboiler to prevent them from rising to the surface and causing the waterto boil over during the operation of boiling the clothes.

It consists, essentially, of an open-work frame adapted to fit looselyin the boiler, with a handle by which it can be introduced or removed, asupplemental slidable frame guided to move with relation to the mainframe, so as to bind and lock the latter in place after it has beenplaced within the boiler, and curved plates attached to frames andconverging inwardly and upwardly, so as to direct the boiling watertoward the center of the boiler.

It also comprises details of construction, which will be more fullyexplained by reference to the accompanying drawings, in which Figure 1is a'bottom view of my attachment. Fig. 2 shows the device in positionin the boiler.

My invention is designed for use in boilers of any form where it isdesirable to keep the contents from rising to the surface by theebullition while it takes place and also to prevent the liquid frombeing thrown out of the boiler by violent ebullition.

In the present case I have shown my device as adapted to fit an oblongboiler with rounded ends and vertical sides; but it will be manifestthat it may be adapted to any form of boiler by making it of a shape tocorrespond with the particular boiler in which it is to be used. As hereconstructed, it consists of a rim A, of heavy wire, having transverseand radial wires B extending toward the center from the rim, so as toform an open grillwork of the wires with intermediate spaces, as shown,I have here shown the wires which extend to the rounded ends of theframe as diverging radially from points which are approximately thecenters of the curves. The first two wires from the straight sidesextend approximately parallel and unite with the radial wires. Theintermediate wires connecting with the straight sides extend toward thecenter and then are curved outwardly in each direction, so that theyunite in two groups, one near the center formed of each of the curvedends, and the wires are here secured by bands 0 and by soldering orotherwise fixing them rigidly. Between these two clamps G a stout wire bextends centrally and longitudinally, and at about the middle it is bentto form a single turn 0, which serves as one of the guides for themovable portion of the frame, aswillbehereinafterdescribed. Upon eachside of this central wire are two other wires D, which are also bent toform coils D a little above the coil 0', and these coils D serve asfulcrums for the lever E, which is formed of a twisted wire, the bightof which is separated to form an operating-handle, and

the ends are bent to enter the coils D and form the fulcrum, about whichthe lever is movable. This exterior wire frame A is of a size to fitinto the boiler, as before described, and it may be pressed down uponthe clothes or other substance which is to be boiled after the boilerhas been sufiiciently filled therewith. 1

In order to lock the frame in place, I have shown a supplemental curvedend A, made of wire, having a guide F slidable in a single turn or coilof the longitudinal radial rod B, which extends to the center of thecurve of the main frame A, this coil making a guide, through which therod connected with the end of the curved frame A is slidable. The endsof the wires A are then brought together at a point near the coil 0, andthence extend parallel through this coil, which thus serves as a guidefor this end of the movable frame. The ends of these guide-wires arethen turned over to make a loop, as shown at a, and this loop receives awire G, the bight of which passes through the loop, and the ends arethen bent inwardly and pass through a coil or turn e, made in the wiresof the handle E. By this construction it will be seen that when thehandle E is moved to one side or the other the guide-wires of the movable frame will slide in the guiding-coils, so that when moved in onedirection the supplemental frame A will be drawn inward and standapproximately in line above the end of Y the frame A, so that it can beeasily introduced into the boiler.

. After it has been pressed down to its proper position the lever E isthen moved in the opposite direction, forcing the end A outward until itpresses against the interior of the boiler, thus forcing the oppositeend of A against the opposite end of the boiler, and the frame will thusbind closely and retain itself in position.

The connection between the link F and the handle-sockets e is such thatwhen the lever is turned these sockets pass down just below a linethrough the fulcrum-points, and thus lock the parts and prevent themovable portion A from returning.

In order to prevent the water from boiling over during strong ebullitionand also to direct it so that a circulation will take place, I haveshown curved plates H fixed to the frames AA, these platesconverginginwardly toward the upper edges, so that the boiling waterstriking the interior of the plates will be thrown toward the center,and this will produce a circulation, as the water will again returntoward the bottom of the boiler through the central portion, beingforced up at the outer sides or ends and returning continuously.

I is a wooden handle suitably secured to the central portion of theframe and standing high enough above it so that it can be easily graspedfor the purpose of introducing or removing the device.

Having thus described my invention, what I claim as-new, and desire tosecure by Letters Patent, is

1. An attachment for boilers consisting of a main reticulated framefitting approximately the shape of the utensil and movable therein, asupplemental frame movable in guides upon the main frame and a lever bywhich it may be extended so as to bind the device within the boiler.

2. An attachment for boilers consisting of a main reticulated frame, thecentral longitu? dinal wires of which are bent to form guidingloops, asupplemental frame slidable with relation to the main frame havingguide-rods connecting with its opposite ends and slidable in the loops,a lever centrally fulcrumed to the frame,'a link connecting said leverwith one end of the slidable frame whereby the movement of the leverwill extend or retract the movable frame.

3. An attachment for boilers consisting of a main reticulated framefitting loosely within the boiler, a supplemental frame with guideswhereby it is slidable with relation to the hand. I
